Re: "I accidentally wrote a Gemini server"
@gim, something causes a double free in OpenSSL (because I do no malloc or free), and I have to track it down.
I will get rid of that space in the request as well.

I get a connection error with Telescope Browser: "Can't parse IRI".
*EDIT*
Works on Lagrange. Maybe Telescope browser is a little to restrictive concerning the specs.

Nice. Works fine for me (in diohsc), though I get what looks like a buggy error message on requesting a non-existent file: "50 no can do i" (missing a 't'?). That happens in particular at /, I guess you'll want to serve index.gmi there.

By the way, if you want to optimise things further, you might consider implementing RTT0 ("early data") mode (while being careful to handle replay attacks; iirc that just means that you shouldn't accept the same ticket twice).

The message is correctly idiomatic with a subtle reference to Hall and Oats.
Also, current not configured to serve directories.

@stack fyi as of Fri Sep 12 06:24:12 PM UTC 2025 I get a hang when trying to access spell.ddns.net:10965/index.gmi with my pxc client and Lagrange. With pxc I can see the header 20 text/gemini but then the connection just stays open. For fuzzing the OpenSSL issue you could consider trying to pipe random data to it with /dev/urandom - that has been a good stress test for me in the past.

@ingrix, I've been actively whumping on it so you probably caught it in-between updates or during a few minutes I had it down.
I integrated timeouts, fixed a couple of deadlock issues, and I think it is kind of working.
Do you have a script for stress-testing the server?
🚀 ingrix · 2025-09-12 at 20:08:
@stack if I were smart I probably would, but right now I just hammer on things by hand. I'll start putting some stuff into a script. My tire-kicking last night involved connecting via nc and sending some random data, feeding it misformatted urls, sending it properly formatted urls, directory traversal attempts, etc. I'll hammer on it some more and post the script somewhere.

Don't worry, the bots will find it eventually and then the fun really starts.

It's working pretty smoothly on Lagrange desktop.
